| dc.description.abstract | In this research, we study the ability of LEO satellite constellations to handle data traffic. LEO satellites offer a number of advantages over traditional space based communications via geosynchronous orbit satellites (GEO). However, these advantages come at the price of complexity. We study the use of GEO satellite data communication systems and their shortcomings to better understand the implications of using LEO systems. We then study several proposed LEO constellations, and develop a simulation model for the Teledesic LEO constellation. We show how Teledesic deals with traffic and the effects of satellite failures. We develop recommendations that improve the robustness of this system. The contributions of this research are: A study of the use of GEO satellite systems for data communication. A study of the popular proposed LEO constellation systems. Construction of a model of the Teledesic constellation. A study of the effect of how Teledesic deals with traffic and with failures. A proposed set of modifications to Teledesic to improve performance. | en |
